LOS ANGELES -- Chris Brown has been charged with two felonies, including assault likely to cause bodily injury and making criminal threats, according to court documents.

The 19-year-old R&B singer, who is free on $50,000 bail, is expected to appear in court later Thursday.

Los Angeles police arrested Brown on Feb. 8 and booked him on suspicion of making criminal threats. Police said at the time a woman identified Brown as her attacker during an early morning dispute in an upscale Los Angeles neighborhood.

A source familiar with the situation has identified the woman as Brown's girlfriend, fellow music star Rihanna.

A phone message left for Brown's attorney and publicist was not immediately returned.
